Abstract
MéTODO PARA A FORMAçãO DE PARTìCULAS DE óXIDO DE FERRO DE PEQUENO TAMANHO, PARTìCULAS DE óXIDO DE FERRO, PREPARAçãO COMPREENDENDO AS MESMAS, MéTODOS PARA A PRODUçãO DA REFERIDA PREPARAçãO, PARA A FORMAçãO DE PIGMENTO E DE CATALISADOR E PRODUçãO INDUSTRIAL. A presente invenção refere-se a um método para a formação de partículas de óxido de ferro de pequeno tamanho compreendendo as etapas de preparar uma solução aquosa inicial compreendendo pelo menos um dos íons férricos e complexos desses, em uma concentração de pelo menos 0,1 % p/p de ferro e um pH maior do que cerca de 1,5; manter a dita solução em uma temperatura menor do que 55<198>C por um tempo de retenção no qual a hidrólise ocorre, a extensão da dita hidrólise sendo suficiente para diminuir o pH por pelo menos 0,2 unidades, em que o dito tempo não excede 14 dias, para formar um sistema contendo uma solução modificada; e ajustar as condições no dito sistema por pelo menos uma das etapas de aquecer a solução modificada para elevar a temperatura dessa por pelo menos 10<198>C; elevar o pH da solução modificada por pelo menos 0,3 unidades; e diluir a solução modificada por pelo menos 20%; pelo qual são formadas partículas, em que a maioria das partículas formadas estão entre cerca de 2 nm e cerca de 500 nm em tamanho.
